On his OTN blog today Chris Jones announces the release of the latest Oracle database and Instant Client libraries (188.8.131.52) for the linux OS:
The Oracle 184.108.40.206 Instant Client libraries are now available on Linux x86 and x86_64 platforms from the Instant Client home page. And they'll soon be uploaded on ULN for customers with Oracle Linux support to install via the update server. If you are one of the (not so?) few users of command line PHP then you might want to grab the new client because it has Oracle bug 9891199 fixed. You'll also need OCI8 1.4.3 from PECL.
The bug this corrected caused a shutdown delay that caused issues with command-line users and their scripts. Unfortunately, the details of the bug are only available to those with an Oracle subscription. This update will not prevent you from connecting to older versions of the Oracle databases.
